libcurl-minimal does not require libbrotli, libidn2, libssh, libpsl, and openldap.
curl-minimal does not require libmetalink.
Using the -minimal packages could transitively help to save additional dependencies and, consequently, a lot of disk space.
The -minimal packages can still be "upgraded" to libcurl-full and curl-full in layered images if necessary. Both the variants provide compatible API/ABI.
Note that curl-full does not require libmetalink either these days (see bug https://bugzilla.redhat.com/show_bug.cgi?id=1967213 for details) but curl-minimal is still much smaller than curl-full due to the reduced amount of documentation.
The proposed change is now implemented in ubi9-container: https://bugzilla.redhat.com/1994521
